Senior Rails Full-Stack Developer

About Hubstaff
Hubstaff helps remote teams work smarter with industry-leading workforce analytics, time tracking, scheduling, and payroll automation software used by 140,000+ users globally.
We’ve been fully remote for over a decade and believe remote work is one of the biggest shifts in modern work. We’re profitable, product-led, and building for the long term.

The Role
We’re hiring a Senior Rails Full-Stack Developer to join our Growth team — a fast-moving engineering group focused on experimentation, user experience, and business impact. This isn’t a traditional feature factory role. Growth engineers at Hubstaff are deeply involved in ideation, experimentation, analytics, and outcomes — not just implementation.

We’re looking for engineers who are driven by outcomes over output and who thrive in environments where speed, learning, and ownership matter. Success in this role means thinking beyond tickets and contributing to the full lifecycle of experiments: ideation, implementation, measurement, iteration, and learnings. You’ll work closely with Product, Design, Data, and Marketing to launch experiments quickly, learn fast, and improve conversion, activation, retention, and customer experience across the platform.

What You’ll Do
Build and scale features using Ruby on Rails, Hotwire, Tailwind, and modern frontend tooling

Launch rapid growth experiments with ultra-fast turnaround times

Own projects and experiments from idea to outcome — not just delivery

Scope-cut strategically to maximize learning velocity and business impact

Work with tools like Statsig, Segment, Metabase, and Customer.io

Analyze metrics, events, experiment results, and user behavior to guide decisions

Balance technical quality with experimentation speed

Improve performance, reliability, and UX across the platform

Collaborate asynchronously with a high-performing remote team

What We’re Looking For
5+ years building production web applications

Strong Ruby on Rails experience

Strong frontend experience with Hotwire/Turbo/Stimulus + Tailwind

Experience with React, Vue, or similar modern JS frameworks

Product-minded engineer with strong ownership mentality

Comfortable operating in fast-moving, experimentation-heavy environments

Strong understanding of metrics, event tracking, experimentation, and data-informed decision-making

Ability to think through tradeoffs, risks, and business impact — not just technical implementation

Bias toward action with a “ship, learn, iterate” mindset

Experience working remotely and asynchronously

Stable work history with multi-year tenure preferred

Nice to Have
Experience with Statsig, Segment, Metabase, or Customer.io

Experience scaling SaaS platforms

Background in growth/product experimentation

Familiarity with Docker, Kubernetes, AWS/GCP

Location
Hiring in: Argentina, Brazil, Poland, Romania, Spain, Portugal

Compensation
$45–60 USD/hour

Long-term contractor role

Why You'll Love Working With Us

Autonomy to move quickly, test ideas, and shape solutions beyond implementation

Long-term product and engineering focus with meaningful technical challenges
